Well, it actually fails to build as part of a dependancy when building kde:

=> Verifying package for ../../devel/SDL
make: don't know how to make arts\. Stop

make: stopped in /opt/pkgsrc/devel/SDL
*** Error code 2

Stop.
make: stopped in /opt/pkgsrc/misc/kdeaddons3

Looks like there is a bug in kde Makefiles somewhere. How can I run it in debug
mode??
